So After using an Access port for a little over 6 months, I decided to swtich things up a bit. There was nothing wrong with my AP or the power but it lacked one feature that i have wanted to use in the past few years. 2step rev limiting.
Specs: 07 335i 6mt sport DCI, Muffler delete and JB4 g5 iso(map 1) 2step set at 3500(had 4-5 lbs of boost)
